Abstract :
The work presents a single monolithic wide band VCO for multi-standard radios. Analysis on a differential switched capacitor circuit is performed. Its impact on phase noise and power dissipation is especially addressed. The analysis is demonstrated and verified in a fully integrated CMOS VCO that consumes 2.7 mA from a 1.8 V supply and operates with a wide frequency band from 3.5-5.3 GHz. The measured phase noise is less than -110 dBc/Hz at 1 MHz offset within the entire tuning range.
